What reviewers say

Sony Bravia 8 II 77-inch OLED TV

Owners and reviewers rate the Bravia 8 highly for contrast, color accuracy and motion, calling it one of the best-looking OLEDs for film. The recurring complaints are brightness in bright rooms and the price premium over LG's C-series.

What people mention
  • Picture contrastPraisedOwners say blacks are deep and HDR highlights pop against dark scenes.
  • BrightnessMixedReviewers find it bright enough for most rooms but dimmer than the brightest QD-OLED and Mini-LED rivals.
  • MotionPraisedSports and games look smooth thanks to the 120Hz panel and Sony's processing.
  • Viewing anglesPraisedColor and contrast stay consistent from the sides, so wide seating works.

Questions and answers

Which is better for a bright living room?
The LG. Its OLED evo panel with Brightness Booster Ultra and the Reflection Free Premium coating hold up better against daylight and glare. The Sony's standard OLED panel and lighter anti-glare treatment struggle more with strong reflections.
Which is better for gaming?
The LG, on paper. It reaches 165Hz VRR in 4K with under 0.1ms response, while the Sony tops out at 120Hz. Both have HDMI 2.1 and low lag, so the Sony is still a solid console TV.
Is the Sony worth stepping up to if I have a big room?
Yes, if size is the priority. A 77-inch screen gives a far more cinematic image at normal sofa distance, and Sony's processing and screen-speaker audio are strong. The LG cannot match that scale at 48 inches.
Which has better sound out of the box?
The Sony. Acoustic Surface Audio+ uses the panel itself as the speaker, so dialogue and effects come from where they appear on screen. The LG relies on conventional speakers and benefits more from a soundbar.
Does the LG support Dolby Vision and the Sony not?
Correct. The LG handles Dolby Vision, HDR10 and HLG, plus Dolby Atmos. The Sony supports HDR but not Dolby Vision, which matters if you stream a lot of Dolby Vision content.
Which lasts longer?
Both are OLED and carry the same long-term risk of panel wear from static logos and news tickers. Neither has a clear durability edge; the LG's newer evo panel is tuned brighter, which can matter for burn-in over many years of heavy use.
